COLLAPSIBLE TUBE.

Specification of Letters lPatent.

Patented Apr. 2?, 1915.

Application filed February 13, 1913. Serial No. 748,066.

To all whom it may concern Be it known that T, WILLIAM Romans, a citizen of the United States, residing at Chicago, in the county of Cook and State nozzle which serves as aspreader to distribute the liquid over the surface to which it v has been applied and to provide a sanitary stopper particularly adapted to seal the aperture.

Other objects will hereinafter appear, the novel combinations of elements being pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side elevation'of atube constructed in accordance with the principles of my invention; Fig. 2 is a sectional view of atube with the cap removed applying liquid'to a plane surface; Fig. 3 is a side elevation of one form of sealing cap; Fig. 4 is a sectional view of the head of the tube with a cap of preferred form applied thereto; Fig. 5 is a sectional view of the preferred form of cap; and Fig. 6 shows a modified form 1 of sealing cap.

' of the, tube anda reduced neck portion 12,

tilt

is formed with an outer inclined or beveled face 13, with a nozzle or outlet opening 1 1 in the end thereof.

In practice the tube is filled with any desired material and is closed at the end opposite the head 11 so that the material contained therein is forced out throu h the opening 14,upon a surface to which it is to be applied, as illustrated in-Fig. 2.

Although the neck portion 12 may be of any shape, it is preferably circular in cross section, and in order to prevent the material in the tube from exuding at any time, a cap 15 is provided. This cap comprises a pin 16 projecting from an inclined surface 17, the inclined surface corresponding to the beveled end of the neck portion 12 and the pin 16 being of a size to accurately fit the opening 14 and of a length to project somewhat within the tube. For convenience in retaining the cap on the head of the tube, and in order to keep the contents of the tube free from dust and dirt, the cap 15 is preferably provided with extending sides 18 which are adapted to fit the neck portion 12 closely. If desired, the sides 18. may be omitted producing a stopper 19 as shown more clearly by Fig. 6. The head of the cap 15 may also be provided with a knob 15' r by means of which the cap is more readily removed from the tube if it should happen to stick.

The stopper is easily removed from the tube, the paste or other material is applied by means of the inclined surface 18, and after being used the cap is readily placed in .osition over the end of the tube to seal it rom dust and dirt and for preventing the material within the tube from being discharged therefrom until the cap is again taken off.

' What I claim is:

1. A collapsible tube having a'thickened perforated end with a beveled end spreading surface, and acap adapted to embrace the extremity with an inner beveled surface corresponding with and closely' fitting the beveled end and having an inner projection to close the perforation when the cap is fitted closely over the end of the tube.

2. A collapsible tube having a beveled extremity with a perforation therein, and a cap for embracin the extremity having an inner beveled surface corresponding thereto and a pin projecting from the beveled sur- A face adapted to fit in the perforation.

3. A collapsible tube having a head formed integral therewith at one end and a circular unthreaded neck portion with a perforated beveled extremity, and a circular unthrea ied cap therefor having a beveled surface corresponding to the beveled extremity and a pin projecting therefrom and adapted to enter the perforation in the beveled extremity in a direction parallel with the sides of the tube.

4. A collapsible tube having a beveled projecting at an angle from the beveled face of the cap adapted to enter the perforation at the end of the tube in the direction of its length, and unthreaded sides projecting from the cap at the edges of the beveled sur-' face in the same direction as the pin to embrace the extremity of the tube.

5. A collapsible tube having a beveled perforated extremity, and a cap therefor adapted to surround the extremity having a beveled inside surface adapted to cooperate with and fit closely the beveled extremity and a pin projecting therefrom adapted to enter the perforation in the end of the tube parallel with the length of the tube.

6. A collapsible tube having a thickened head portion at one end formed of the same material as the tube and provided with an unthreaded neck of reduced cross section having a beveled outer extremity with a perforation therein at an angle to the surface, a cap adapted to fit over the reduced portion closely with an inner beveled surface corresponding to the beveled extremity of the reduced portion, and having a pin pro jecting at an angle from the inclined surface and adapted to enter the perforation parallel with the length of the tube and fit closely in the perforation in the end of the tu e.

7. The combination of a collapsible tube having an integral thickened portion at one end with a beveled extremity having a perforation parallel with the length of the exuding.

In testimony whereof I have signed my 1 name to this specification, in the presence of two subscribing witnesses, on this 10th day of February, A. D. 1913.

WILLIAM RODIGER.
